So - here is a video of the 'flow' in my tank - I was doing a water change - and there were some bubbles.
Its interesting in the paper in 2011 - they used in an aquaculture center - with a streaming flow (for 30 minutes) - but I would guess they were also continuously 'adding it' since it wasnt (I think) a recirculating system. It was quite effective (they said the number of deaths (from velvet dropped from 200-3000 fish/day to 10 or so).The current thought is to use as a bath, but with minimal water agitation so that it doesn’t “react” like you’ve mentioned.
